[Champ Concept] Walbyorn the Ursine Stormcaller

With Volibear getting a rework and playing a more integral role in the lore of Freljord, a friend of mine and I figured it would be cool to make a member of his shamanistic cult into a league champ. We came up with a barbaric shaman like character who's meant to be played in the botlane as a vanguard support, healing his allies and becoming tougher to kill through battle. Hope y'all enjoy!

Appearance: A tall very stout human (Think professional strongmen or powerlifters) with long blond hair braided into Nordic style ponytail. Beard is more reddish blonde but also long and braided Nordic style. Eyes have yellowish white glow to them. Wears a bearskin draped over his shoulders like a cape of sorts, has studded leather fur trimmed forearm bracers, and fur trimmed pants. Has a bear skull belt buckle. On his chest, upper arms, and face, tribal tattoos befitting the Freljord depicting storms, battle, bears, and various other runes. Wields a doublesided great axe with Celtic/Nordic style runes etched into the broad side of the axe. On his feet are fur trimmed boots.

Passive: Fury of the Storm Basic attacks on enemy champions taunt them for a short duration, forcing them to attack Walbyorn. This effect cannot trigger more than a few seconds on the same target.
